Naya [18.7K]

The total area of two square windows is 1,025 in.^2. each side of the larger window is 5 in. longer than the sides of the smalle
vampirchik [111]
The area of a square is expressed as:

Area = s^2

We are given the area of both windows. We will use this value for the calculations. We set s as the side of the larger window and a for the smaller window.

Total area = Area larger + area smaller
1025 = s^2 + a^2

Since it was said that the side of the larger window, s is 5 in longer than the side of the smaller window, a (s = 5+a) then:

<span>1025 = s^2 + a^2
</span>1025 = (5+a)^2 + a^2

simplifying we obtain,

a = 20 inches

If the sum of five times a number and two times the same number is increased by 4, the result is 25. Find the number.
Nezavi [6.7K]

Answer:

The number x = 3

Step-by-step explanation:

Let 'x ' be the positive integer

Given data If the sum of five times a number and two times the same number  and the same number is increased by 4 and the result is 25

sum of five times a number is 5 x and same number two times is 2 x and increased by 4 (addition) then result is equal to 25

so finally  5 x +2 x +4 = 25

               7 x + 4 = 25

subtracting '4' on both sides , we get

               7 x = 25 -4

               7 x = 21

dividing '7' on both sides, we get

\frac{7x}{7} = \frac{21}{7}

x=3

Therefore the number is x = 3

<u>Verification :</u>-

5 x +2 x +4 = 25

substitute x = 3 in above equation

15+6+4 = 25

25 =25

<u>Final answer</u> :-

The number is 3
